Textcraft

Wow, this app is EXACTLY what I need! I just had one “wish list“ item, which is to transform an ellipsis (...) into a long dash (–). I went to try to contact the developer with this suggestion, but I could not find a way to do that, other than this review. But in general, this app is a revelation! Many thanks!

I misunderstood what this app does from the description ... but the thing it actually does is ALSO very useful! One can type in any snippet of text, and the app will immediately present an array of dozens of alternative snippets, most of them either making simple changes (like a d d i n g w h i t e s p a c e or Changing Things to Title Case) or doing some clever processing (like rapbqvat in Rot13) or — coolest of all — taking advantage of exotic Unicode characters for formatting like sᴍᴀʟʟ ᴄᴀᴘs or 𝔅𝔩𝔞𝔠𝔨𝔩𝔢𝔱𝔱𝔢𝔯 or uʍop ǝpısdn or 🅑🅤🅑🅑🅛🅔🅢 or š̷̟p̶̰̙͂õ̴̤̲̾õ̴̤̲̾k̸̛̝͒y̸̺̓͊ d̸̢̩̚ỉ̵̹͎̀a̷͇͝c̶̱͒r̶͓͑ỉ̵̹͎̀t̴̪̩̍ỉ̵̹͎̀c̶̱͒a̷͇͝ļ̵̳̕š̷̟.

This gives a bunch of transformations, and the developer has been very responsive to feature requests. I'm really happy that the app now vends an Action so I can perform a transformation within a different app (though it still requires pasting the transformed text, which might be an iOS limitation), and that you can now pin favorite transformations to the top of the (long) list (though it's not very discoverable — long press the transformation to get a context menu).
